CQFFEE=MAKER= Specification of Letters Patent.

Patented Feb. 12, 1907, 1905. $erial lie-241,872.

Be it known that I, ARTHUR E. WHITE, a citizen of the United States,cage, in the county of Cook nois, have invented certain T0 (ZZZ 117mm itDuty concern: I l l residing at Uhiand State of Illinew and useful lImprovements in Coilee-islakers, of which the following is aspecification.

The invention relates to appliances for making eoll'ee in which theground collee is placed in a vessel and submitted to the action ofboiling water in the vessel, and after in fusion the liquid is allowedto pereolate or drip from the receptacle in which the cofl'ee is made.

The objects of the invention are to improve the construction andoperation of the receptacle as regards the placing of the coffee andwater therein for infusion and allowing the liquid to percolate or driptherefrom, to enable the receptacle to be placed on end for receivingthe coffee and water and inverted i without any trouble andinconvenience to allow the liquid to percolate or drip into the l coffeepot or urn, to facilitate the application and withdrawal of thestraining medium I through which the coilee percolates or drips, and tosuspend the receptacle in which the l coil'ee is made by a bail, soarranged as to allow of the ready inversion of the receptacle for makingthe coil ee and for allowing the i l l l l l l l l l l l coffee topercolate or drip from the receptacle.

The invention consists in the features of construction and combinationsof parts hereinafter described and claimed.

In the drawings, Figure l is a side elevation showing the receptacle inposition for making the coffee, Fig. 2, a sectional elevation with thereceptacle in position for making the cefl'ee; Fig. 3, a sectionalelevation with the receptacle inverted to permit the liquid to percolateor drip therefrom,- Fig. l,

' a top or plan view with the straining material in place,- Fig. 5, anelevation oi the band for i holding the straining material in place, andFig. 6 an elevation showing the receptacle in i which the coilee isdrawn mounted on an urn, with the urn broken away at its upper end. fThe receptacle or vessel A can be made of sheet metal or other suitablematerial and preferably has a tapering body or wall a and l an end walla, with the end (6 of the recepl tacle or vessel opposite to the endwall a l open. The end wall a has formed therewith i or suitably securedl wardly body thereto a funnel B, inextending and having a side wall orb terminating in a straight end wall I), l

; sel after been placed therein is covered by a strainer with aninterior screw-thread to receive the body of a closing-plug C, having afingerpiece 0, by means of which the plug can be inserted and withdrawn.

The funnel B is for the purpose of facilitating pouring the coflee backinto the receptacle or vessel for renewed or further infusion with thegrounds to give additional strength, and the plug 0 remains in positionduring the process of infusing the coffee and the percolating 0rdripping of the liquid from the receptacle or vessel A into the coffeepot or urn.

A band or hoop D, having an interior diameter slightlygreater than theexterior diameter of the smaller or open end a of the receptacle orvessel A, furnishes the means for retaining a strainer in place over theopen end of the receptacle or vessel A for the liquid to percolate ordrip through the strainer. The band or hoop D on oppcsitesideshas springcatches or hooks (Z, which when the hoop or band is in place take over aflange or rib cl on the exterior of the receptacle or vessel A. and lockthe hoop or band in place, and to facilitate the attachment andwithdrawal of the hoop or band handles or grabs (Z are provided adjacentto the spring hooks or catches in the arrangement shown.

A bail E, made of wire or other suitable material bent into shape tohave a cross or end bar 6 with a grab F/ thereon and side arms or barsa, furnishes a means for handling the rceptacle or vessel. The end ofeach side bar or arm is inwardly turned to form a trunnion e terminatingin a ball 6'' and entered into an ear 6' on the body or wall a of thereceptacle or vessel, thereby suspending the receptacle or vessel Awithin the bail E in such manner that it can be turned into the positionshown in Fig. 1 or into the position shown in Fig. 3, as may be requiredfor infusing the coilee or for percolating or dripping the coifee. Tiebody or wall a of the vessel or receptacle has on opposite sides grabsor handles f to assist in inverting or reversing the position. of thereceptacle or vesopen end of the receptacle or vesthe ground coflee andthe water has sel, and the g,ot cloth or suitable material, so that whenthe vessel is turned into the position shown in Fig. 3 the liquid willpercolate or drip through the strainer.

In use the vessel or receptacle is placed on its larger end, as shown inFig. 1, with the inc IIO

hoop or band i) and the strainer g removed, the filling-funnel torre'e'ntering the cotlee being closed by the plug C, as shown in Fig. 2.he ground coilee is placed in the receptacle or vessel and the requiredamount of boiling water is added thereto and the strainer g is p acedover the open end of the vessel and secured in place, so as to be taut,by slipping the hoop or band D onto the end of the receptacle or vesselfor the spring catches or hooks (Z to engage the rib or llange d andlock the hoop or iand in pl ice, so as to hold the strainer lirinly inposition. After the infusion. of the coffee for the desired period oftime the receptacle or vessel A is raised by the bail and brought overthe coffee pot or urn I into which the coffee is to be deposited, andwhen in position the operator, through the bail E and the grab or handle f, inverts the receptacle or vessel A, bringing it into the positionshown in Fig. 3, so that the liquid can percolate or pass through thestrainer 7 into the coffee pot or urn F, and during the percolation ordripping of the liquid from the receptacle or vessel A into the coffeepotor urn the plug 0 remains in position, closing the tunnel B, asulnciency of air being provided to effect percolation by not fillingthe vessel or receptacle A to its full capacity or by loosening slightlythe plug C, maintaining, however, a suliicient closure to prevent theescape of the aroma. In case the co'liee is not of sutlicient strengthwhen first made the liquid can lie drawn from the co'fi ee pot or urnand the funnel B opened by removing the plug G and the coffee returnedto the receptacle or vcs el A to receive additional strength from theground colic-e, and when the made co'ltee has been returned to thereceptacle or vessel A to the quantity requircd the tunnel B is closedby the plug C and the liquid allowed to percolate or pass through thestrainer and into the cofiee pot or urn, the opening of the plug Callowing a fresh supply of air to enter while the liquid is beingreturned to the vessel or receptacle A to be redrawn. The maintaining ofthe receptacle closed keeps all the aroma and flavor within thereceptacle or vessel, so that when. the liquid escapes in its finishedcondition the codes will have therein all the aroma and flavor of theberries oi the coffee.

The tunnel B facilitates the return of made collee, if not of sullicientstrength, to the interior of the receptacle or vessel A for the liquidto receive ail ional strength from the grounds in the receptacle orvessel, and the tunnel is only opened for the purpose of returning themade collee to the receptacle or vessel.

he bail E is shown in Figs. 1, 2, and 3 in its raiseil position, whichis the position it occupies for carrying the rec otacle or vessel andfor turning the rec acle or vessel end for end; but this bail in use isfree to drop down the same as an ordinary bail and is only raised intoits elevated position when it is desired to carry the receptacle orvessel and turn the receptacle or vessel for its larger end to be downto make the coffee or for its smaller end to be down to percolate ordrip the liquid.

The hoop or band D furnishes a ready means for the attachment andremoval of the strainer, it being understood that the strainer isremoved when placing the ground co'l'l'ee and the boiling water in thevessel and is replaced so as to be in position to allow the liquid topercolate or drip therefrom when the vessel or receptacle A is inverted,as shown in Fig. 3, for the liquid to pass into the cotl'ee pot or urn.

The funnel B in addition to furnishing a means for returning the madecoffee to the receptacle or vessel for additional infusion to increasethe strength also enables a greater quantity of coffee to be made thanthe amount of water and coffee which can be placed in thereceptacle-that is to say, if the receptacle or vessel were adapted tocontain enough coffee and water to make two gallons of cotlee it can beused for making an additional gallon, it only being necessary to placein the receptacle or vessel the required amount of coii ee to producethree gallons of the made coffee, and the additional gallon can beproduced by opening the funnel and adding another gallon of water aftera gallon of the liquid has been withdrawn, and the added gallon of waterwill produce from the coffee in the vessel or receptacle the thirdgallon of made cotlee, it being understood that after the gallon ofwater has been poured into the vessel or receptacle the funnel is to beclosed by the plug, and when closed. the liquid will percolate or passthrough the strainer the same as if no water had been poured into thevessel over the quantity adapted to be contained in the receptacle orvessel.

What I claim as new, and desire to secure by Letters Patent, is

1. In a coilee-malrer, the combination of an invertible vessel havingside walls and a wall at one end furnishing an unobstructed base orsupport for the vessel, and open at the other end, a tunnel for the endwall in wardly projecting into the chamber of the vessel and adapted todirect the flow of liquid tliere'into, a closure for the vessel adaptedto be rigidly inserted into place to prevent leakage when the vessel issupported on its closed end, a band encircling the exterior of thevessel at its open end and furnishing a rest for the vessel on the urnwith the open end of the vessel entered into the top of the urn, and. astrainer encircled by the band and clan perl thereby over the open endof the vessel, substantiallyas described.

2. In a coiieeanaker, the combination of an invertible vessel having atapered side Wall and a Wall at the larger end and open at the smallerend, a band encircling the eXterior of the vessel at its open end andhaving a stop supporting the vessel on the urn, spring catches on theband, and a flange circuniferal on the side Wall engaged by thespring-catches and detachably connecting the band with the end of thevessel, and a strainer entered over the open end of the vessel and drawntaut and held in place by inserting the band in position on the end ofthe vessel, substantially as described.

3. In a coffee-maker, the combination of a vessel having a tapered sideWall and a Wall 1 at the larger end and open at the smaller end, a bandencircling the exterior of the vessel at its open end and furnishing arest for the vessel on the urn with the open end of the vessel enteredinto the top of the urn, a circumferential flange on the side Wall, aspring connection between the band and circumferential flange, and astrainer entered onto the open end of the vessel and drawn taut byforcing the band into position on the end of the vessel, substantiallyas described.
